However one insider has told how while the group advertises itself as a place for people to meet and begin meaningful relationships, the group is actually a “non-stop stream of porn which anyone can join”.

The insider added: “I joined the group with a blank profile, no picture, no nothing. You have to request to join, but they do not do any checks at all.

“I just wanted to take a look around and see what it was about, but it was very explicit.

“Then over the last three weeks they have introduced this ‘Happy Hour’, where everyone is told to share pictures of themselves naked or hardly wearing anything.

“There’s men posting pictures of their member, women doing similar. It doesn’t end.

“It’s horrific that people can just make something that just resembles porn and nothing is done about it.”

One user said they would happily continue to pose naked pictures, despite complaints flooding in

The insider said: “I have a 12-year-old cousin who has Facebook.

“They could sign up for this for all they care and see all that.

“This could be used by predators, people looking for revenge porn, anything.

“Facebook took down a few of the images when people complained, but hardly any of them.”

The XXX NETWORK: Facebook's rules on nudity

Facebook has outlined its rules on nudity…

People sometimes share content containing nudity for reasons such as awareness campaigns or artistic projects.

We restrict the display of nudity because some audiences within our global community may be sensitive to this type of content – particularly because of their cultural background or age.

In order to treat people fairly and respond to reports quickly, it is essential that we have policies in place that our global teams can apply uniformly and easily when reviewing content.

As a result, our policies can sometimes be more blunt than we would like and restrict content shared for legitimate purposes.

We are always working to get better at evaluating this content and enforcing our standards. We remove photographs of people displaying genitals or focusing in on fully exposed buttocks.

We also restrict some images of female breasts if they include the nipple, but we always allow photos of women actively engaged in breastfeeding or showing breasts with post-mastectomy scarring.

We also allow photographs of paintings, sculptures and other art that depicts nude figures.

Restrictions on the display of both nudity and sexual activity also apply to digitally created content unless the content is posted for educational, humorous or satirical purposes.

Explicit images of sexual intercourse are prohibited. Descriptions of sexual acts that go into vivid detail may also be removed.

Facebook requires everyone to be at least 13 years old before they can join and will close or suspend any accounts of users it discovers are younger.

The Sun Online has approached three admins in the group for comment.

None of them have responded.

A spokesman for Facebook said: “We want people to have a positive experience on Facebook which is why we have easy ways for our community to report content and profiles that they find upsetting or they feel break our Community Standards.

“After The Sun brought this group and related images to our attention, we investigated and found that the images have already been removed from this group.

“It is our policy that we restrict the display of nudity because some audiences within our global community may be sensitive to this type of content – particularly because of their cultural background or age.”
